I still have the parrot but I froze him ? I guess a necropsy would still show a broken bone or something like that ? Blood. tissue breakdown would probably prevent any blood analysis ?
Yes, there will be limits, but a good pathologist can still be able to learn something from a necropsy. Definitely any broken bone, like the keel, would be found. I’m not sure if they could tell if the bird was suffocated, but possibly there would be signs. Certainly if the trachea was crushed.
